本实用新型涉及液压回转钻机钻进技术领域，特别是一种液压回转钻机防卡钻装置。The utility model relates to the drilling technical field of a hydraulic rotary drilling rig, in particular to an anti-jamming device for a hydraulic rotary drilling rig.
背景技术 Background technique
钻机钻头的回转和进给是液压回转钻机的主要运动。这两部分运动分别靠液压系统回转马达的进油口和进给油缸来实现。现在的钻孔作业中，操作者需根据岩层的情况，通过手动换向阀分别控制钻头回转运动和进给运动，回转马达的进油口的最高工作压力(不同的钻机此参数有所不同)通过泵站系统安全阀设定。进给油缸压力由操作者根据岩层情况通过远程调压阀随时调整。当岩层发生改变或遇到塌孔时，钻头回转压力会急剧升高，有时会达到或超过系统的正常工作压力。这时操作者应停止进给，稍将钻头退出，待回转压力下降到正常值再实施进给，此动作需多次重复，确保回转压力不超过系统的正常工作压力值，否则钻头有被岩石夹层挤死或被塌落的碎石卡住，发生卡钻现象。此项操作要求操作者精力应高度集中，时时监测系统回转压力，操作较为繁琐，一旦发生卡钻事故，排除难度较大。The rotation and feed of the drilling rig bit are the main movements of the hydraulic rotary drilling rig. These two parts of motion are realized by the oil inlet of the rotary motor of the hydraulic system and the feed cylinder respectively. In the current drilling operation, the operator needs to control the rotary motion and feed motion of the drill bit through the manual reversing valve according to the conditions of the rock formation, and the maximum working pressure of the oil inlet of the rotary motor (this parameter is different for different drilling rigs) It is set by the safety valve of the pumping station system. The pressure of the feed cylinder is adjusted by the operator at any time through the remote pressure regulating valve according to the rock formation conditions. When the rock formation changes or encounters hole collapse, the rotary pressure of the drill bit will rise sharply, sometimes reaching or exceeding the normal working pressure of the system. At this time, the operator should stop feeding, withdraw the drill bit for a while, and then start feeding after the rotary pressure drops to the normal value. This action needs to be repeated many times to ensure that the rotary pressure does not exceed the normal working pressure value of the system, otherwise the drill bit may be damaged by rocks. The interlayer is squeezed to death or stuck by the collapsed gravel, resulting in drill sticking. This operation requires the operator to be highly concentrated and monitor the system rotation pressure at all times. The operation is relatively cumbersome. Once a stuck pipe accident occurs, it is difficult to eliminate it.

本实用新型是通过下述技术方案来实现的：The utility model is achieved through the following technical solutions:
本实用新型的液压回转钻机防卡钻装置，包括第一手动换向阀、第二手动换向阀，进给油缸、回转马达的进油口、油箱，其特征在于：在回转马达的进油口和第一手动换向阀之间的管路中增设一压力传感器，在进给油缸和第二手动换向阀之间的回路中增设电磁换向阀。The anti-jamming device of the hydraulic rotary drilling rig of the present invention comprises a first manual reversing valve, a second manual reversing valve, an oil feed cylinder, an oil inlet of a rotary motor, and an oil tank, and is characterized in that: the oil inlet of the rotary motor A pressure sensor is added in the pipeline between the port and the first manual reversing valve, and an electromagnetic reversing valve is added in the circuit between the feed cylinder and the second manual reversing valve.

本实用新型的一种液压回转钻机防卡钻装置的工作原理是：The working principle of the anti-jamming device of a hydraulic rotary drilling rig of the present utility model is:
在回转马达的进油口和第一手动换向阀之间的管路中增设一压力传感器；在进给油缸和第二手动换向阀之间的回路中增设一电磁换向阀。正常工作时，泵站提供的压力油通过手动换向阀的切换来控制回转马达的进油口的转动方向和进给油缸的运动方向，回转系统的压力油经第一手动换向阀的左位进入压力传感器、回转马达的进油口，驱动钻头回转；与此同时进给系统的压力油经第二手动换向阀的左位进入电磁换向阀的右位，进给油缸伸出，驱使钻头进入孔底。当岩层发生改变或遇到塌孔时，回转马达的进油口的进口压力会急剧升高，当达到压力传感器预先设定的安全压力时，卡钻现象将要发生，此时压力传感器发出电信号，并传给通过导线与之相连接的电磁换向阀的电磁铁DT1带电，驱使电磁阀换向，进给油缸开始反向动作将钻头退出，当回转压力下降到压力传感器设定的安全压力以下时，压力传感器电信号中断，电磁换向阀靠弹簧复位，进给油缸活塞杆伸出继续带动钻头实施进给，此动作可能要重复几次。A pressure sensor is added in the pipeline between the oil inlet of the rotary motor and the first manual reversing valve; an electromagnetic reversing valve is added in the circuit between the feed oil cylinder and the second manual reversing valve. During normal operation, the pressure oil provided by the pump station controls the rotation direction of the oil inlet of the rotary motor and the movement direction of the feed cylinder through the switching of the manual reversing valve. The pressure oil of the slewing system passes through the left side of the first manual reversing valve. The bit enters the pressure sensor and the oil inlet of the rotary motor to drive the drill bit to rotate; at the same time, the pressure oil in the feed system enters the right position of the electromagnetic directional valve through the left side of the second manual directional valve, and the feed cylinder extends. Drive the drill bit into the bottom of the hole. When the rock formation changes or encounters a collapsed hole, the inlet pressure of the oil inlet of the rotary motor will rise sharply. When the safety pressure preset by the pressure sensor is reached, the stuck pipe will occur. At this time, the pressure sensor sends out an electrical signal. , and transmitted to the electromagnet DT1 of the electromagnetic reversing valve connected to it through the wire to be electrified, driving the electromagnetic valve to reversing, the feed cylinder starts to reverse the action and the drill bit is withdrawn, when the rotary pressure drops to the safety pressure set by the pressure sensor At the following time, the electrical signal of the pressure sensor is interrupted, the electromagnetic reversing valve is reset by the spring, and the piston rod of the feed cylinder is stretched out to continue to drive the drill bit to perform feeding. This action may have to be repeated several times.
本实用新型的有益效果是：由于本装置在回转马达的进油口进油口端的管路中增设一压力传感器，在进给油缸和手动换向阀之间的回路中增设一电磁换向阀。当回转马达的进油口压力出现异常时，装置会自动处理孔内复杂情况，有效防止卡钻事故的发生和钻杆发生偏移。The beneficial effects of the utility model are: since the device adds a pressure sensor in the pipeline at the oil inlet end of the rotary motor, an electromagnetic reversing valve is added in the circuit between the feed oil cylinder and the manual reversing valve . When the oil inlet pressure of the rotary motor is abnormal, the device will automatically deal with the complex situation in the hole, effectively preventing the occurrence of drill stuck accidents and the deviation of the drill pipe.
